Chemical Composition, Plant Genetic Differences, and Antifungal Activity of the Essential Oil of Helichrysum italicum G. Don ssp. microphyllum (Willd) Nym
Journal of agricultural and food chemistry, 2003•ACS Publications
The chemical composition of the essential oil of the Sardinian dwarf curry plant [Helichrysum
italicum G. Don ssp. microphyllum (Willd) Nym] was studied. Genetic analysis suggested the
presence of two chemotypes; morphological and chemical differences confirmed the
presence of two chemotypes (A and B). The maximum yields were 0.18 and 0.04%(v/w) for
flowering tops and stems, respectively. The concentrations of nerol and its esters (acetate
and propionate), limonene, and linalool reach their highest values during the flowering …

The chemical composition of the essential oil of the Sardinian dwarf curry plant [Helichrysum italicum G. Don ssp. microphyllum (Willd) Nym] was studied. Genetic analysis suggested the presence of two chemotypes; morphological and chemical differences confirmed the presence of two chemotypes (A and B). The maximum yields were 0.18 and 0.04% (v/w) for flowering tops and stems, respectively. The concentrations of nerol and its esters (acetate and propionate), limonene, and linalool reach their highest values during the flowering stage both in flowers and in stems. Besides the essential oil, type B showed an interesting antifungal activity.
